4 Function, section -chmer directionl vlves of type -.WE re solenoid operted directionl spool vlves. They control the strt, stop nd direction of flow with the dditionl option of djusting the spool switching time. These directionl vlves siclly consist of the housing (1), one or two solenoids (), the control spool (3), s well s one or two return springs (). The two spring chmers () re connected y connecting pssge. As the spool switches, the flow is displced from one spring chmer to the other vi this pssge. If the cross-sectionl re of this connecting pssge is reduced y throttle then the switching time chnges ccordingly. The T chnnels re isolted from the spring chmers. This mens tht switching pulses do not ffect the control spool (3) nd thus soft switching of the spool cn e chieved. In the de-energised condition, the control spool (3) is held in the centrl or initil position y return springs () (except for impulse spools). The control spool (3) is operted y wet pin solenoids (). In order to ensure correct functioning, cre must e tken to ensure tht the pressure chmer of the solenoid is filled with oil. The force of the solenoid () cts on the control spool (3) nd pushes it from its neutrl position to the required end position. Thus, the required flow direction from to A nd B to T or to B nd A to T is chieved. When the solenoid () is de-energised the control spool (3) is returned to its neutrl position y the return spring (). A hnd override (), optionl, enles the control spool (3) to e moved without energistion of the solenoids. Adjustle spool switching time (only with DC solenoids) The optionl instlltion of throttle screw () or orifice (8) - see elow - offers the possiility of incresing the switching time With throttle screw type -.WE 10../..CG../C..

The ctul time is dependent upon the individul system (e.g. pressure, flow nd viscosity). When rectro fitting or modifying throttling system, cre must e tken tht the fluid volume in the spring chmers nd the connecting ore () is retined, s this is prerequisite for the smooth opertion of the switching time djustment.
